Patent CA-2116087-A1 (CA)
Title: Schottky junction type field effect transistor and method of manufacturing the same
Inventor: NAKAJIMA SHIGERU
IPC: H01L29/08
Filed: 1994-02-21
Abstract: ABSTRACT OF THE DISCLOSURE    This invention has as its object to easily obtain a MESFET free from output distortion.  For this purpose, in this invention, an n+-type layer is formed at a substrate position spaced apart from a gate electrode by a distance of a side-etch amount Lg-n+.  The n+-type layer has an impurity concentration and thickness such that a surface depletion layer generated depending on a surface level on the drain-side does not almost extend to the drain-side.          An n'-type layer as an intermediate concentration layer has an impurity concentration and thickness such that a drain-side end portion of a channel depletion layer generated upon applying a voltage to the gate electrode extends to the drain-side with an increase in this applied voltage.  Moreover, the n+-type layer, a distance Lg-n+, and the n'-type layer are formed to have a relationship in which a ratio of an extension length L of the drain-side end portion of the channel depletion layer from the drain-side end portion A of the gate electrode to the drain-side, to a gate length Lg falls within a predetermined range.  Therefore, according to this invention, the long gate effect and the effect for the drain current in accordance with the square characteristics cancel each other, and an FET output changes linearly in response to an input.

Abstract: A metatarsal guard inserted in the upper of a safety shoe is made of plastic and defines an arch extending from the sole of the shoe on one side of the wearer's instep to the sole on the other side of the wearer's instep.  The metatarsal guard includes a rear impact-absorbing portion having longitudinal slits cut in the sheet material to form a transversal series of longitudinal tongues that spread apart to follow the movement of the foot when the wearer is walking.   An integral flap is formed in the sheet material at the distal end of the central tongue. This central tongue is folded to apply the flap to the top surface of the tongues and thereby distribute the load upon the  impact  of  a  falling  object.    The metatarsal guard is further provided with two lateral slits  cut  in  the  sheet  material  and  extending transversely to facilitate flexion of the metatarsal guard upon flexion of the wearer's foot.   A front portion of the metatarsal guard includes at least one longitudinally extending tongue bent to be applied to the top surface of the toe cap whereby load applied to the metatarsal guard is also applied to the toe cap.

Title: Method and apparatus for maximizing vehicle braking effectiveness and control
Inventor: BREEN MICHAEL T
IPC: B60T8/176
Filed: 1994-08-22
Abstract: METHOD AND APPARATUS FOR MAXIMIZING VEHICLE BRAKING EFFECTIVENESS AND CONTROL               Abstract of the Disclosure Optimum braking effectiveness and control of a  vehicle  are  obtained  by  continually  evaluating estimated  values  of  friction  coefficients as  they increase with decreasing vehicle velocity during vehicle braking and by increasing brake pressure accordingly to maintain the pressure  just under  a value at which vehicle control is compromised.   This is enhanced by determining a maximum pressure that can be applied to each brake sight while maintaining the rate of change of the articulation angle between a tractor and trailer of the vehicle equal to zero.   A further enhancement is obtained by estimating critical vehicle velocity as a function  of  steering  angle,  thus  enabling  braking effectiveness  and  control  to  be  a  function  of maneuvering conditions.
Patent CA-2130975-A1 (CA)
Inventor: NACSON SABATINO
IPC: G01N30/64
Filed: 1994-08-26
Abstract: ABSTRACT           A surface ionization detector for detecting organic molecules such as illicit drugs and non-organo-nitrate explosives includes a heated surface and a collector electrode.  A sample containing trace amounts of the organic molecules in ambient air is directed over the heated surface maintained at a temperature in the range of 500°C to 800°C, thereby causing the molecules to decompose into fragments.  A polarization voltage between 18V and 24V is applied to ionize the fragments which are then collected by the collector electrode.  An electrometer connected to the collector electrode measures the current and a change in the current indicates the presence of ionized fragments, and thereby indicates the presence of the organic molecules.  The temperature of the heated surface and the polarization voltage are optimized for detection of particular organic molecules.

Title: Method and apparatus to increase efficiency of systematic codes
Inventor: KULESA ANTHONY G
IPC: H03M13/00
Filed: 1994-11-17
Abstract: A method and apparatus for increasing the coding efficiency of a digital data transmission system from k/n to (k+1)/n by truncating a check bit from a generated checkword and adding an extra information bit prior to transmission. The encoding algorithm at the receiver borrows the added information bit to replace the truncated check bit in order to perform error detection and correction n the entire codeword.   If an error is detected at the shared bit position, the shared bit is not corrected by the decoding circuit since a detected error in that position is more likely a result of bit inversion due to replacement than due to a transmission fault.   The coding efficiency of the transmission system is increased from k/n to (k+1)/n while the number of bit errors correctable by the system is only reduced to, on the average, t-(1/2) for some range of BER's.

Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive.  Several alternative communication paths are available, such as the previously mentioned modem, a parallel printer port, a conventional serial port, a cradle assembly connected to the host computer, and various wireless short distance techniques such as radio frequency or infrared transmission.  The computer can readily communicate with other sources, particularly to a host desktop computer, to allow automated synchronization of information between the host and the handheld system.  Preferably the remote synchronization is performed at several user selectable levels.  When the handheld computer is in a cradle and actively connected to the host computer, automatic capture of updated data in the host computer is performed.  Several synchronization techniques are utilized to keep track of different types of files.  In addition, while communication is established the handheld computer can enter a remote control mode, allowing the user access to files and applications not included in the handheld computer.
